Heat pumps are electrically powered, mechanical devices used to take heat from the air. But what about when it’s cold outside? Even cold air contains a certain amount of heat, and heat pumps are very good at removing that heat.
In the winter, the heat pump extracts the heat from the cold air and transfers it to the inside of your home, keeping it warm. Conversely, in the summer, the heat pump removes that warm air from inside your home and sends the heat outdoors, replacing it with cool air inside.
- Moving heat instead of generating it saves you money. Remember: there’s a cost to generating heat by burning fuel or gas.
- The process is electro-mechanical, so there are no fuel bills.
- Provides both heating and cooling at lower costs.
- They are highly efficient efficient (if auxiliary heating strips remain off).
You will typically find heat pumps in areas of the country that have more moderate climates, because you can only remove so much heat. That being said, below are some disadvantages to heat pumps.
- They cannot transfer enough heat in colder climates.
- They are equipped with auxiliary heating strips to augment when outside temperatures are low. When the auxiliary heat strips are energized, they consume huge amounts of electricity.
It’s important to mention that as technology advances, heat pumps are being seen in less temperate climates. Some homeowners will pair heat pumps with oil or gas furnace units to offset costs.
Our discussion has primarily been about the most common type, the air to air heat pump, but there are three types of heat pumps:
- Air to Air: These are the most common, and they draw their heat from the air as the name implies.
- Water Source: Draws heat from an outside water source.
- Geothermal: Extracts heat from the ground. These are becoming more popular but can be quite costly.
Overall, heat pumps can be an excellent alternative to furnaces and air conditioners. Our team at M&M Mechanical, Inc. will be able to answers to any questions you might have, so contact us today for more information.
